Some buttons on the right hand of the consoles don't register anymore --namely the delay and start/stop button. The left side buttons work fine, however. I can choose the types of wash cycles (quickclean, normal, etc.) but I'm unable to get the machine going because the start button won't register.

Is this an issue with the touch panel or the console board where this thing is attached? I peeked at the console board (yellow color pcb), but I didn't see any signs of burnt capacitors or any other tomfoolery.

It can be either the control panel (keypad) or the control board.
Unfortunately Frigidaire do not give the pinouts for the keypad so it is difficult to test.
The usual way is to check the keys with a meter and if it checks out OK then replace the control board.
It can be checked but you need to guess your way as to what tracks (pins) go to what keys.

Have you tried removing power from the unit for a couple minutes to see if it will reset?

I would try the following cleaning procedure to see if that fixes it.

If the above do nothing I would replace the keypad.
Note that this is just a guess nas it is a more likely cause.

Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector. Use electronics contact cleaner or isopropyl alcohol.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
